1. Introduction

The Wireless Clip-on Headset HS-21W can be connected to a compatible mobile phone that supports Bluetooth wireless technology. This allows you freedom to make and receive calls while on the move or in the office. Read this user guide carefully before using the headset. In addition to this user guide, read also the user guide for your phone, which provides important safety and maintenance information. Keep the headset out of reach of small children.
Bluetooth wireless technology
The Bluetooth wireless technology makes it possible to connect compatible communication devices without using cables. A Bluetooth connection does not require that the phone and the headset be in line of sight, but both devices should be within 10 meters of each other. Connections can be subject to interference from obstructions, such as walls, or other electronic devices. The HS-21W headset is specially designed for compatible Nokia mobile phones that support Bluetooth wireless technology. The headset can, however, be used with any compatible devices that support the compatible Handsfree or Headset profiles. (Here, a profile is a set of Bluetooth wireless technology commands that the phone uses to control the headset). The HS-21W headset is compliant with the Bluetooth Specification 1.1 supporting the following profiles: Headset Profile 1.1, Handsfree Profile 1.0. However, interoperability between the HS-21W headset and other Bluetooth-enabled
products is not guaranteed because it depends on compatibility. Check with the manufacturers of other devices to determine their compatibility with this device.

2. Getting started

Note that there may be restrictions using Bluetooth wireless technology in some locations. Check with your local authorities or service provider.

Disconnecting the headset
You can disconnect the headset from your phone when, for example, you want to connect another device with your phone using the Bluetooth wireless technology. The headset can be disconnected in the following ways:
Switch off the headset. Disconnect the headset in the Bluetooth menu of your phone. Move the headset more than 10 meters away from the phone. The headset is also disconnected if its battery becomes discharged. Note that you do not need to delete the pairing with the headset to disconnect it. When you reconnect a paired headset, you are not asked for its passcode.
Connecting the paired headset
To connect the headset to your phone, switch on the headset, make the connection in the Bluetooth menu of your phone, or press and hold the answer/ end key of the headset. You can set your phone to accept Bluetooth connection requests from your paired headset. In this case, the headset can connect to your phone automatically when it is switched on. In Nokia phones this can be done by changing your paired devices settings in the Bluetooth menu.

Troubleshooting

If you cannot connect the headset to your phone, do as follows: Make sure that the headset is charged, switched on (the green indicator light blinks) and paired with your phone. Make sure that the Bluetooth feature is activated on your phone.
Check that the headset is within 10 meters of your phone and that there are no obstructions between the headset and the phone, such as walls or other electronic devices. Check the pairing information list of the headset; it may be full. The headset can store the information of up to eight phones at a time.

You can switch the active call between the headset and a compatible Nokia phone. To switch the call from the headset to a phone and vice versa, press and hold the answer/end key for 2 seconds, or use the respective function in your phone.
Using the headset with several phones
The headset can be paired with up to eight phones but connected to only one phone at a time. The phone that was first paired with the headset is called the default phone. The phone that was last used with the headset is called the last used phone. If the headset is switched on within 10 meters of several paired phones, the headset will try to connect to the default phone within a few seconds.

If the headset cannot connect to the default phone (for example, when it is switched off or its user rejects the connection), the headset tries to connect to the last used phone within a few seconds. If the headset cannot connect to either of the phones, it remains discoverable for other phones. If you want to use the headset with a paired phone that is not a default phone or last used phone, make the connection in the Bluetooth menu of your phone.

Resetting the headset

You can reset the headset to its original settings (for example, to change the default user of the headset). When you reset the headset, all of its settings, including pairing information, are cleared. To reset the headset, press and hold the power key and the volume up key for 10 seconds. After the headset has been reset, it beeps twice, and the red and the green indicator lights alternate for several seconds.

4. Battery information

Your device is powered by a rechargeable battery. The full performance of a new battery is achieved only after two or three complete charge and discharge cycles. The battery can be charged and discharged hundreds of times but it will eventually wear out. When the talk and standby times are noticeably shorter than normal, buy a new battery. Use only Nokia approved batteries, and recharge your battery only with Nokia approved chargers designated for this device. Unplug the charger from the electrical plug and the device when not in use. Do not leave the battery connected to a charger. Overcharging may shorten its lifetime. If left unused, a fully charged battery will lose its charge over time. Temperature extremes can affect the ability of your battery to charge. Use the battery only for its intended purpose. Never use any charger or battery that is damaged. Do not short-circuit the battery. Accidental short-circuiting can occur when a metallic object such as a coin, clip, or pen causes direct connection of the positive (+) and negative (-) terminals of the battery. (These look like metal strips on the battery.) This might happen, for example, when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object. Leaving the device in hot or cold places, such as in aclosed car in summer or winter conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery between 15C and 25C (59F and 77F). A device with a hot or

cold battery may not work temporarily, even when the battery is fully charged. Battery performance is particularly limited in temperatures well below freezing. Do not dispose of batteries in a fire! Dispose of batteries according to local regulations. Please recycle when possible. Do not dispose as household waste.

Care and maintenance

Your device is a product of superior design and craftsmanship and should be treated with care. The suggestions below will help you protect your warranty coverage. Keep all accessories and enhancements out of the reach of small children. Keep the device dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that will corrode electronic circuits. If your device does get wet, remove the battery and allow the device to dry completely before replacing it. Do not use or store the device in dusty, dirty areas. Its moving parts and electronic components can be damaged. Do not store the device in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics. Do not store the device in cold areas. When the device returns to its normal temperature, moisture can form inside the device and damage electronic circuit boards. Do not attempt to open the device other than as instructed in this guide. Do not drop, knock, or shake the device. Rough handling can break internal circuit boards and fine mechanics. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the device. Do not paint the device. Paint can clog the moving parts and prevent proper operation. All of the above suggestions apply equally to your device, battery, charger, or any enhancement. If any device is not working properly, take it to the nearest authorized service facility for service.

If the headset cannot connect to the default phone (for example, when it is switched off or its user rejects the connection), the headset tries to connect to the last used phone within a few seconds. If the headset cannot connect to either of the phones, it remains discoverable for other phones. If you want to use the headset with a paired phone that is not a default phone or last used phone, make the connection in the Bluetooth menu of your phone. 26

Resetting the headset

You can reset the headset to its original settings (for example, to change the default user of the headset). When you reset the headset, all of its settings, including pairing information, are cleared. To reset the headset, press and hold the power key and the volume up key for 10 seconds. After the headset has been reset, it beeps twice, and the red and the green indicator lights alternate for several seconds.

Battery information

4. Battery information
Your device is powered by a rechargeable battery. The full performance of a new battery is achieved only after two or three complete charge and discharge cycles. The battery can be charged and discharged hundreds of times but it will eventually wear out. When the talk and standby times are noticeably shorter than normal, buy a new battery. Use only Nokia approved batteries, and recharge your battery only with Nokia approved chargers designated for this device. Unplug the charger from the electrical plug and the device when not in use. Do not leave the battery connected to a charger. Overcharging may shorten its lifetime. If left unused, a fully charged battery will lose its charge over time. Temperature extremes can affect the ability of your battery to charge.

Do not short-circuit the battery. Accidental shortcircuiting can occur when a metallic object such as a coin, clip, or pen causes direct connection of the positive (+) and negative (-) terminals of the battery. (These look like metal strips on the battery.) This might happen, for example, when you carry a spare battery in your pocket or purse. Short-circuiting the terminals may damage the battery or the connecting object. Leaving the device in hot or cold places, such as in aclosed car in summer or winter conditions, will reduce the capacity and lifetime of the battery. Always try to keep the battery between 15C and 25C (59F and 77F). A device with a hot or cold battery may not work temporarily, even when the battery is fully charged. Battery performance is particularly limited in temperatures well below freezing.
Use the battery only for its intended purpose. Never use any charger or battery that is damaged.

Do not dispose of batteries in a fire! Dispose of batteries according to local regulations. Please recycle when possible. Do not dispose as household waste.

Care and maintenance

Your device is a product of superior design and craftsmanship and should be treated with care. The suggestions below will help you protect your warranty coverage. Keep all accessories and enhancements out of the reach of small children. Keep the device dry. Precipitation, humidity and all types of liquids or moisture can contain minerals that will corrode electronic circuits. If your device does get wet, remove the battery and allow the device to dry completely before replacing it. Do not use or store the device in dusty, dirty areas. Its moving parts and electronic components can be damaged. Do not store the device in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics.

Do not store the device in cold areas. When the device returns to its normal temperature, moisture can form inside the device and damage electronic circuit boards. Do not attempt to open the device other than as instructed in this guide. Do not drop, knock, or shake the device. Rough handling can break internal circuit boards and fine mechanics. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the device. Do not paint the device. Paint can clog the moving parts and prevent proper operation. All of the above suggestions apply equally to your device, battery, charger, or any enhancement. If any device is not working properly, take it to the nearest authorized service facility for service.
